What’s New in Math and Multimedia?

High School Mathematics

We have learned a lot about mathematics and technology last year, and will learn more this year.  For students, I will concentrate on senior high school mathematics and other  middle school topics which we have not yet discussed.  For teachers, I will discuss tools that can help in teaching at the same time making most of the internet and Web 2.0 technologies.

Inequalities in GeoGebra — the long wait is over

GeoGebra

One of the best features added to GeoGebra 4.0 (still in Beta)  is graphing inequalities.  The image below were sample inequalities graph plotted in version 3.9.73.0, which, as of this writing, can be downloaded here. So far, the latest GeoGebra Beta can only graph linear inequalities. The feature is till very unstable, so updates may cause for it not to work properly. Michael Borcherds, lead developer of GeGebra, told  me that they are not yet sure if polynomial inequalities will be included in the 4.0 version.

Linear inequalities in GeoGebra 4.0 Beta

GeoGebra 4.0will probably be released late this year or early next year.

Thank You GeoGebra Team.
